Customer Question
I have a P0305 misfire...
I have a P0305 misfire code on a 2002 dodge dakota. I can rundown what I've done if u think u have ideas.
Plugs and wires, distributor rotor, manifold gasket all done. Fuel injectors checked, compression ok.
Was told engine computer may be issue. Ordered a vin programmed remanned computer and installed.
Ran 100 miles then check engine light back on again with same code, so I returned the computer and went back to the
Old computer. Mechanic ran sea foam through several times. It seemed to help some. Check engine light would stay on for 1-200 miles, go off for 1-200 miles and keep going on and off like that for a while. Now on all the time.

Customer reply replied 2 years ago
Done that. It doesn't move away from cylinder 5.
Dodge Mechanic: xsvector, Auto Mechanic replied 2 years ago

if the injector is good and your positive its getting spark and the compression is good it is a internal failure sticking valve worn cam or something
